Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PCB board clamping, in particular to a semiconductor first piece PCB board clamping component. Background Art
[0002] Semiconductor PCB board is an electronic component used to support semiconductor elements. It is composed of a circuit layer formed by conductive materials and an insulating layer formed by insulating materials. Semiconductor PCB board can be used as a carrier of the circuit and provide electrical connection and physical support. In the production process of semiconductor PCB board, it is very important to inspect the first or first batch of products. By testing the products, problems that may affect product quality can be found, and timely measures can be taken to prevent batch defects or scrap. In the inspection process of semiconductor PCB board, the product needs to be clamped by a fixture to keep the product in a stable state during the inspection process;
[0003] However, in actual operation, the clamping force of the fixture is often a challenge. If the clamping force is too small, the PCB board may move during the inspection process, resulting in reduced inspection accuracy or even inspection failure. If the clamping force is too large, both sides of the PCB board may be damaged due to excessive pressure, which not only affects the structural integrity of the PCB board, but may also affect the functionality of the PCB board.
[0004] In order to solve the above problems, the present application proposes a semiconductor first PCB board clamping assembly. Utility Model Content
[0005] Based on the technical problems existing in the background technology, the utility model proposes a semiconductor first PCB board clamping component.
[0006] The utility model provides a semiconductor first PCB board clamping assembly, comprising a workbench and a clamping seat arranged on the workbench;
[0007] The clamping seat is provided with two clamping plates and a driving member for driving the two clamping plates to move closer to or away from each other;
[0008] Elastic assembly parts are installed on both sides of the clamping seat, and a through opening is opened in the middle of the two clamping plates. A limit rod passing through the two openings is installed between the two elastic assembly parts. A reset pressure piece for pressing down the elastic assembly part is rotatably installed on the side of the clamping seat, and a blocking block located at the front end of the reset pressure piece is installed on the workbench.
[0009] Preferably, the elastic assembly includes an assembly block, two of the assembly blocks are respectively installed on both sides of the clamping seat, and the two clamps are located between the two assembly blocks. An assembly rod is installed at the bottom of the assembly block, and the assembly rod slides through the bottom of the clamping seat. A spring is sleeved on the assembly rod, and the two ends of the spring are respectively connected to the assembly block and the clamping seat, and the limit rod is connected between the two assembly blocks.
[0010] Preferably, the reset pressure piece includes a special-shaped pressure block, which is connected to the side of the clamping seat through a rotating shaft and is located on the outside of the assembly block. A torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are respectively connected to the special-shaped pressure block and the clamping seat. A pressure opening is opened on the side of the assembly block close to the special-shaped pressure block, and a guide roller located in the pressure opening is installed on the special-shaped pressure block.
[0011] Preferably, the driving member includes a servo motor, which is installed at the rear end of the clamping seat. The output end of the servo motor is connected to a gear, and the upper and lower ends of the gear are respectively meshed and connected to racks, and the two clamps are respectively connected to the two racks.
[0012] Preferably, guide rails are provided on the adjacent sides of the two clamping plates.
[0013] The above technical solution of the utility model has the following beneficial technical effects:
[0014] By means of the elastic assembly, the limit rod and the reset pressure piece, the two clamping plates can be driven to approach each other through the driving member to adjust the width between the two clamping plates. Then the clamping seat can be moved forward so that the reset pressure piece on the clamping seat abuts against the blocking block. The reset pressure piece presses down the elastic assembly, and the limit rod connected to the elastic assembly also moves downward. Then the plate can be inserted into the guide rail slideway provided in the two clamping plates to move the clamping seat to its original position. After the force applied to the reset pressure piece is cancelled, it can return to its original position to release the limitation on the elastic assembly. The limit rod can be pushed upward by the elastic assembly, and the plate can be positioned by the limit rod. This structure can limit the plate through the linkage of the elastic assembly, the limit rod and the reset pressure piece, thereby solving the problem of excessive or insufficient clamping force of traditional clamps and ensuring the stability of product clamping.
